The custodians were rulers for as long as she could remember. She distantly recalled a time when they weren't there, what she would later learn about in history classes as the time before the Great Shift. The custodians, it was said, came out of charity, love and compassion. They came to fix humanity. And fix it they did.
The newer generations were hybrids. A better form for humanity, it was said. And it was.
The custodians ranged all shades of dark gray to dark purple, almost black, and the smooth skin on their many tentacles had a deep, almost pearl-like, sheen to them. Their eyes were like pools of molten gold and copper. Their six legs and one sting were long and slender, an intricate dance of soft curves and sharp turns. They did not speak vocally, but communicated telepathically, their soft voices whispering in humanity's minds.
All humans had been promised to them. Not as reward or as sacrifice, but as a token of the same love they had bestowed on humanity. As a sign of integration and a step in building a shared and better future. For this purpose, every human who had come of age had a custodian chosen for them, a special one, whom they would accept and love.
Thirty was that age, and that day at midnight, the implant Emerald had been given all those year ago started sending its signal between her legs. Five minutes after she stated feeling aroused, the door opened and a server entered into her room. She was a slightly older woman sworn to the union centers, choosing to remain unpartnered and serve as a facilitator to the human-custodian unions that were initiated within. Emerald didn't know this one, nor did she expect to. She knew that mating servers took this role exclusively, meeting each union only once.
The server was wearing a long black dress that hid most of her body and face, as well as the customary facial mask that made sure no one knew their server's identity. She stepped close to Emerald, who was lying on the bed between thin sheets, and leaned her thumb, over her underwear, against Emerald's clit. A shudder or pleasure and fear took her for a moment, and she felt her pulse rising and her body turn hot. Emerald knew better than to oppose and let out a sigh instead. She didn't want this woman touching her. She wanted this touch. Another thumb stroke on her clit made her take a deep breath and try to let go as another wave of arousal overtook her.
"Let go," she thought, and took another breath. She closed her eyes but still couldn't shake away the feeling. "Stop touching me," she thought at the thumb pressing against her, "please more." She knew the implant was messing with her body.
Next the server's thumb slipped over the opening of her cunt, still over Emerald's underwear. She knew the server could very well feel the heat emanating from there. Almost mindlessly, she pushed slightly against her thumb, but the server kept it still.
"Probably measuring my pulse," Emerald thought with frustration, her arousal increasing. She wanted it all to go away. She wanted that finger to slip into her.
After a few still moments, the server spoke: "It seems like you're ready."
Ready. Emerald thought with a mounting sense of horror. She'd already been introduced to her custodian mate, she knew it. The custodians didn't have names, but telepathic signs. Those were specific feelings, like personal scents, that a accompanied each custodian. Whenever a custodian needed to communicate to or about another, they would generate that feeling. She knew her custodian's sign, like a scent, and it repulsed an scared her.
Suddenly, the server slipped a finger inside her, taking her by surprise. Emerald felt a wave of pleasure and increasing arousal return to take center stage in her mind, putting all the rest in a fog of lust and confusion. She sighed again.
"Ready," the thought floated through her mind with fear, between the foggy waves of pleasure and frustration running through her body. She tried not to think of her custodian, and yet felt its menacing image in her mind. The server's finger inside her didn't move, and she pushed herself against it, feeling herself contract and shiver slightly. Her custodian was dark gray ones, with molten gold eyes and a delicate pearl sheen to its skin. Its general shape reminded Emerald of a monstrous fusion between an insect and a cuttlefish. And while the server's finger moved ever so slightly inside her, rippling though her body and making her moan again, the custodian's monstrous shape was looming over in the back of her mind. "Shit," she thought. She was so aroused. She didn't want to be.
Just as suddenly as she slipped it in, the server pulled her finger out, causing Emerald to contract again, relieved that she wasn't being touched anymore, frustrated at the the lost touch.
